Application filed October 3, 1916. Serial No. 123,506.

To all whom t may concern:

Be it lmown that I, HERMAN P. PORTER, a citizen of the United States, residing at Lakeland, in the county of Polk and State inner sash so connected thereto as to be capable of being swung inward and held in open adjusted position for the purpose of ventilation and easily and readily removed therefrom Within the room for the purpose of cleaning and ventilation, and is an improvement on Letters Patent granted under date of October 2 0, 1903, No. 7 42,020.

The main object of this invention is to provide simple, economical, durable and efficient window sashes for windows, so constructed that both the upper and lower inner sash may be swung inward from the upper end thereof to any suitable or desirable eX- tent and held in such adjusted position in order to furnish the necessary ventilation without causing a direct draft, said inner sashes being removable and interchangeable.

Another object of the invention is to provide Window sashes, so constructed that each inner sash carrying the window pane or panes may be readily removed from the sash frame within the room for cleansing purposes, thereby rendering it unnecessary to climb on the outside of a building or upon the window sill thereof in order to clean the window panes, thus avoiding the public gaze as well as the danger to which window cleaners are usually subjected during the window cleanin process. n A further object of the invention is to provide window sashes having safe, durable,

efficient and economical means for locking the sashes together within the window frame, and meanssecured to the sashes and concealed within the same when closed, for adjusting each inner sash inwardly to any suitable extent and holding it in the desired adjusted position to furnish the necessary ventilation for the rooms of a building during[` either its occupancy or vacancy.

he foregoing and such other objects as may appear from the ensuing description are attained by the novel features of construction, arrangement and location of parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the claims appended hereto, it being understood that slight changes in the form, proportion, and minor details of the construction may be resorted to without departing from the spirit or sacriicing any of the advantages of the invention.

Reference now being had to the accompanying drawings which form a part of this specification and in which similar numerals of reference indicate like parts troughout the several views, it will be seen t at Figure l, is a front elevation of the improvements embodying my invention.

Fig. 8, is an enlarged detail view showing in section the upper portion of the inner sash, and in full lines the spring catch tor locking the inner and outer sashes together, and Fig. 9, is an enlarged detail sectional view through the meeting rail of both the upper and lower sashes, showing in Ylull lines the means for locking the sashes to gether.

1n carrying out my invention as illustrated, and which shows a preferred conn struction, the numeral 1, designates a window frame of any well known construction provided with sash weights, cords and pulleys (not shown), such as are ordinarily employed in connection with sliding sashes. 3 indicates the lower outer sash frame and ll, the upper outer sash frame, said sash frames being iitted within the window frame and adapted to slide therein. Each of the outer sash frames 3 and l carries a removable, adjustable and interchangeable inner sash frame 5, adapted to swing out ot the same and to be securely fastened thereto, and each of the frames 3 and 4 is formed on three sides with a suitable groove or rahbet, suchas 6, into which lits a suitable corresponding rabbeted edge 7 of the sash Vtraine 5, said edge 7 overlapping the rabbet 6, to prevent the entrance of rain, dust and cold air. The lower or hinge sides of the frames 3 and 4 are formed with a groove or rabbet 8 on the outer face thereof, and the hinged lower edge of each inner sash trame 5, is provided with an overlapping downwardly projected edge 9, which rests within the groove or rabbet 8, thereby serving to shed the rain outwardly, and the inner and outer sashes are so constructed and connected at their lower ends as to form a watertight and dust-proof joint, which also vserves as a hinge for the swinging sash frame 5, as clearly shown in Fig. l of the drawings.

To each side rail of both the upper and lower outer sashes is pivotally secured the folding arms 10 and 11, the arm 10 being permanently secured to the said side rail, while the slotted end portion 12 of the arm 11 is detachably secured to a headed pin or screw 13, fastened to each side rail of the inner swinging sash 5. The arms 10 and 11 are pivotally connected together by a headed rivet or any other suitable means,fone arm having a series of ribs or corrugations 14C, formed radially thereon at its jointed end, and the other arm having an outward projection 15 formed integral therewith, and adapted to rest between the said ribs there; by locking the swinging inner sash at any desirable adjusted position until it is desired to shut or close the swinging sash, when by slight inward pressure upon the said sash the projection 15 will readily ride over the ribs or corrugations 1d, thus allowing the sash to he closed, and the folded arms to be located and concealed within the recesses 15 and il' formed within the side rails of each of the outer and inner sashes, respectively, as shown in ligs. 3, 4e and 5 of the drawings.

lorined within the upper rail of the upper and lower outer sash near each end thereof is a recess 18, for the reception of a spring locking latch 19, secured to and car ried by the upper rail of theinner sash near each end of said upper rail, each recess 18 being covered by a small metal plate 20 suitably secured to the said outer sashes, and each spring locking latch is provided with a depending metal ring 21 for the manipulation of the said latches.

IlFhe central portion of the upper sash rail ot the outer lower sash is provided with an opening therethrough adapted to receive and carry a spring locking bolt 22 which is adapted to enter a recess 23X formed in the lower rail of the upper outer sash for the purpose of securely looking the upper and lower sashes together.

Surrounding this locking bolt 22 on the outside ot the top rail of the outer lower sash is a small metal plate 28 suitably se* cured to the top rail, and the bolt 22 is provided with a projection or pin 24 projecting from each side thereof, which rests in contact with the outer tace of the plate 23 when the bolt is extracted trom the recess 23X and given a half turn, as shown in Fig. 9.

ln order to properly brace the inner sashes 5, and increase their rigidity, strength and durability, each of said sashes is provided at each corner thereof with a right angular metal plate 25 suitably and securely fastened thereto, as shown in Fig. 1.

By reference to Figs. 1 and 2 of the drawings it will be seen that the ring 21, in each latching bolt 19, of the upper inner sash, is provided with a depending cord 26, having at its lower end a ring 21X, whereby the latching bolt may be easily extracted and the inner sash swung inward to any suitable extent, and while I have shown a cord it will be understood that a chain or ornamental cord of any suitable or desirable construction, Inay be utilized and preferably provided with a ring at its lower end, which may be grasped by the lingers for the easy and proper manipulation of the upper sash for Ventilating purposes.

When it is desired to ventilate the rooms of a house during its vacancy and at the same time prevent entrance of unauthorized persons by means of the windows, it is simply necessary to lock the sashes together by means of the locking bolt 22, then by a slight downward and inward pressure on the rings 21X unlock the locking latches 19 of the upper sash and swing its inner sash inwardly to any desirable extent, thereby providing suitable ventilation during absence from thel premises.

When it is desired to remove the inner upper sashfor cleaning purposes, the lower sash is elevated to contact with the upper portion of the window frame and the upper sash is lowered to contact with the lower portion of the window frame, the sashes being so constructed that when the respective sashes are in this position, the upper bar of the inner sash carrying the locking latches is clear of the lower bar of the lower outer sash, as shown by dotted lines in Fig. 2 and the latch bolts are then extracted; the inner sash is swung inward, and the pivoted locking arms 10 and 11 by a slight upward pressure are reversed and caused to assume the position shown in dotted lines Fig. 4, thus permitting the slotted end of arms 11 to drop downward and automatically release them from their headed securing pin or screw 13, thereby releasing the inner sash from the outer sash when it may be readily removed to a suitable position within the room for cleaning purposes, and in order to prevent the upper outer sash from being returned by the sash weight to its uppermost position while the inner sash is being cleaned, an opening 27, is formed through the side bar of the outer sash adapted to register with a recess 2S, formed in the side wall of the window frame for the reception of Ya suitable pin or nail which will retain the said outer sash until the inner sash is ready to be replaced and locked in the outer sash, which operation is readily accomplished by placing the lower end of the inner sash upon the bottom rail of the outer sash, then lifting the outer slotted end of each folded bar 11 into contact with the headed securing pin or stud 13, when by reversing the dotted line position of the pivoted folding arms by slight downward pressure the arms will be securely attached to the inner sash and by slight outward pressure the inner sash will be closed and automatically locked to the outer sash frame by the sprin locking latches and the upper sashes may t en be returned to their normal position within the window frame. Both the lower and upper inner sashes are removed and replaced in the manner herein referred to.

When the weather is extremely warm and it is desired to obtain a full volume of the outside atmosphere within the room, it is simply necessary to remove both innerA sashes thereby leaving substantially an unobstructed area within the window frame for the ingress of air, as shown in Fig. 3

without interference with the ordinary wire gauze screen usually secured to the outer face of the window frame.

I-Iaving thus described my invention, what I claim and desire to secure by Letters Patent is l. A sash frame, in combination with a sash removably and adjustably fitted in said frame and adapted to swing inward on said frame, a jointed link connection with said frame and removable sash for limiting the inward movement of the removable sash in the sash frame and having a detachable engagement with the removable sash operable automatically to disengage the link when its sections are folded reversely to their collapsed relation, and means carried by said jointed link to retain the removable sash in its adjusted inward position.

2. In window construction, the combination with anouter and an inner sash frame, the inner frame being removably and adjustably secured to said outer frame, said inner frame having three of its sides formed with a rabbet on its outer face and its bottom portion having a downwardly projected rabbet on its inner face, a jointed link connected with both the inner and outer frames for limiting the tilting movement of the 1nner frame in the outer one and havinfg de tachable engagement with the inner rame operable automatically to disengage the link when its sections are folded reversely to their collapsed folded relation, and means carried by said jointed link for lockin the inner sash frame in its suitably open a justed position.

3. In window construction, the combination with an upper and lower outer sash frame, of an inner sash removably and adjustably secured thereto, a pluralityl of locking latches secured to the upper rail of each inner sash, means attached to the locking latches of the upper frame operable from a standing position on the floor to unlatch and tilt said upper inner sash frame to a suitable inward position, and a jointed link connection with each outer and inner sash for limiting the inward movement of the inner sash in the outer one and having detachable engagement with each inner sash operable automatically to disengage the link when its sections are folded reversely to their collapsed folded relation.

4. An outer sash frame, in combination with an inner sash frame, said inner sash frame being removably and adjustably secured to the outer frame, a plurality of locking latches secured to the inner sash frame provided with means operable from a standing position on the floor for unlocking said latches and tilting said inner sash inward, a jointed link connected with the outer and inner sash frame for limiting the inward movement of the inner sash in the outer one and having detachable engagement with the inner sash operable automatically to dieengage the link when its sections are folded reversely to their collapsed relation, and means forming a part of Saidjointed linlr for locking the inner sash frame in its suitably inward position.

5. The combination With a Window-frames, of an outer sash and an inner Sash having lapping rabbeted engagement therewith closing the joints againstv the Weather yet permitting relative tilting oi the inner sash in one direction, and a jointed link connection limiting the tilting play of the inner sash in the outer one and having a detachable engagement With one of the sashes 0perable automatically to dieengage the link when its sections are folded reversely to their collapsed folded relation, the inner sash be- Ving otherwise freely removable from the outer sash.
